NEW YORK (TheStreet) -- Warren Buffett -- the Sage of Omaha and the CEO and chairman of Berkshire Hathaway -- is said to have a favorite metric for gauging the value of the entire stock market.

The metric is fairly simple, too.

It is calculated by dividing the entire market cap of all equities by the total quarterly GDP of the U.S.. Some investors and traders refer to it as "the Buffett Indicator." The metric provides insight into the stock market's total value relative to the growth and output of the entire U.S. economy. 

As of right now, the Buffett Indicator is at its second-highest level in over 50 years. And that's despite the fact that since 2014 started, the S&P 500 is up only 1.5% while the Nasdaq Composite and Dow Jones Industrial Average  are both down roughly 1%.

Is this something to worry about? Take a look at how Buffett's metric has fluctuated since 1950 in the remarkable chart shared below:
